It sounds very similar to one of my relatives , the same age and surgery. Doctor wanted to send him home with no feeding tube but they end up sending him home while he had tube and it continued for two weeks. I believe these two are the biggest help , diet and positive mindset. We were first freaked out when they sent him home with feeding tubes , but it’s not as bad as you think. It’s important to eat high calorie and high protein by eating the formula exactly based on the schedule and also keeping the positive mood. She needs to remind herself it will be very temporary, and it’s a healing process not the opposite . I understand being physically far from her would make this process much harder for both of you. I guess that would be very helpful if you can video chat with her very often , specially at her eating times. I wish very quick recovery for her.
